As frequent indulgers in smoothies and homemade protein shakes, I have to say this recipe is awesome .. originally circulating on FB, its been tweaked to be a bit more of a protein shake. Id say this is more 'inspired by Frosty' than an actual knockoff, but it still tastes great! Enjoy!
almond, rice or soy milk (skim can be used in a pinch)
unsweeteed cocoa powder
frozen banana (optional)
packet of stevia or other natural sweetener
